This particular mp3 player is built around ATmega128 microcontroller that reads data from old 2.5″ laptop hard drive. MP3 player uses STA013 Mpeg decoder IC that sends decoded audio through CS4334 Stereo DAC (24-bit). Player software and hardware files are available for download. Check out for newer versions where various control interfaces like keypad; rotary encoder and remote IR are built.
